Currently have an issue where emails are not working and believe its due to the exchange drive being full. It currently has about 400mb free space left. I am trying to see what would be the best way to proceed to get email flow again. The drive that is almost full is the E:\Program Files\Microsoft\Exchange Server\V14\Mailbox\ directory. I see alot of log files in this directory but from the research i have done they should not be deleted. Any input is appreciated.
